CEMS-CGA, RATA & Certification Services in California (2026): Latest Updates, Benefits, Challenges & How Energy Environmental Solutions, Inc. Helps Industries Stay Compliant
California continues to enforce some of the nation’s most rigorous air quality regulations, making Continuous Emissions Monitoring Systems (CEMS) a critical compliance tool for many industrial facilities. In 2026, regulatory agencies are placing even greater emphasis on Continuous Emissions Monitoring System Certification, Relative Accuracy Test Audits (RATA), Cylinder Gas Audits (CGA), Quality Assurance (QA/QC), and defensible emissions data.
Facilities operating under EPA, CARB, and local Air District permits must ensure their CEMS remain properly certified, calibrated, and maintained to produce reliable emissions data. Failure to perform required audits or certification can result in invalid monitoring data, additional regulatory scrutiny, or permit compliance issues. Recent South Coast AQMD guidance also reinforces documentation, Quality Assurance Plans (QAPs), and certification procedures for new, modified, and recertified CEMS.
At Energy Environmental Solutions, Inc. (EES), we provide complete CEMS Certification, CGA, RATA, QA/QC, and Engineering Support Services to help industries achieve accurate emissions monitoring and regulatory compliance.
